Hi Codeforces!!!

So, solving neatly made problems in Codeforces made me want to do just that. In other words, I want to try problemsetting one day! I got some ideas but many questions as well.

1. How do I begin? (ehe)

2. How do you get good ideas for CP problems?

3. How do I know if the idea is good or not?

4. What practices do I need to become good at problemsetting?

If anyone has anything to say please do so UwU

Thanks in advance!
